What is a CT Scan?

A CT or CAT scan uses X-rays to take cross-sectional pictures of the inside of the body in “slices.” These slices are then reconstructed into an image.

CT studies give more information about the inside of a body than a single X-ray image and may be necessary for your child’s medical treatment. CT scans also result in more radiation exposure than a single X-ray.

The number of CT scans performed on children has increased five-fold over the last 15 years. Ninety percent of those scans were performed at non-pediatric hospitals, often exposing children to unnecessary radiation.
